Best Practice
Always include an XML declaration at the top of your file to specify the version and encoding.
Did You Know?
Unlike HTML, XML is strictly case-sensitive for all element and attribute names.
Tip
Use self-closing tags like <link /> for elements that do not contain any child content to keep your code concise.
Q: What does it mean for XML to be well-formed? A: A well-formed XML document adheres to the basic syntax rules of the XML specification, such as having a single root and correctly nested tags.
Q: Why does the validator say my tags don't match? A: XML is case-sensitive. Check if your opening tag and closing tag use the exact same capitalization, such as <Data> and </Data>.
Q: Can I check for specific schema rules? A: This tool focuses on well-formedness and syntax. It checks if the XML is technically correct rather than checking against a specific DTD or XSD.
